5 Pre-Workout Nutrition Tips You Must Know

Eat a full meal 2–3 hours before training

A balanced meal of 400–600 kcal with carbohydrates, moderate protein, and low fat gives your body time to digest and replenish glycogen stores before you train. Oats + eggs, rice + chicken, and Greek yogurt + fruit are reliable options. Avoid high-fat or high-fibre meals within 90 minutes of training.

Include carbohydrates for strength training

Muscle glycogen is the primary fuel for intense anaerobic exercise. Depleted glycogen means earlier fatigue, reduced reps, and lower peak strength. Complex carbs (oats, rice, sweet potato) 2–3 hours pre-workout or simple carbs (banana, dates) 30–45 minutes before both work well depending on timing.

Include 20–40g protein before training

Pre-workout protein elevates the muscle amino acid pool before and during training, supporting MPS and reducing exercise-induced breakdown. Whey protein 30–60 minutes before is fast-digesting and practical. Even if you train within 2 hours of a protein-containing meal, you’re covered.

Start your session already hydrated

Even 1–2% dehydration impairs strength, endurance, and cognitive performance. Drink 400–600ml of water in the 2 hours before training. Don’t rely on thirst as the indicator — thirst signals dehydration that has already begun. During training: 150–250ml every 15–20 minutes.

Avoid high fat and high fibre within 60–90 min of training

Fat and fibre slow gastric emptying significantly. A high-fat or high-fibre meal within 60–90 minutes of training increases the risk of digestive discomfort, reflux, cramping, and bloating during exercise. Keep pre-workout snacks light and rapidly digestible.
